WASHOUT-PLUG WRENCH.

Application filed June 2, 1925 Serial. No. 34,423.

The device relates to a tool for placing and removing wash out plugs and the like. It is the practice, periodically, to remove the plugs from locomotive boilers to wash them out. It is the usual practice in removing the plugs, which are constructed with rectangular sockets, to use a bar of substantially the same size as the dimensions of the socket for turning the plugs. As the plugs are liable to rust or corrode, thus making it diihcult to turn, and furthermore unless the bar that is used to turn the plug is maintained in an axial position to the plug, the plug is liable to become broken in endeavoring to remove it and when broken considerable time is required to remove the broken plug, this invention has for its object the provision of a tool designed particularly to prevent the breaking of the plug and to insure removal thereof.

To this end the invention comprises a shank having an end adapted to fit the socket oi the plug, and a nut rotatably mounted on the shank designed to engage the threads on the plug to securely hold the shank end in engagement with the plug and also to provide a reinforcement to prevent breaking of the walls of the socket, and insuring removal of the plug under all conditions.

The construction and operation of the device as well as its advantages will be described hereinafter and will be found illustrated in the accompanying drawings, in which Figure 1 is a side View of the improved wash out plug wrench shown in position on the wash out plug,

Figure 2, a longitudinal sectional view of Figure 1, and

Figure 3, an end view of the wrench.

In the drawings similar reference characters will be used to designate corresponding parts throughout the several views.

A Wash out plug is illustrated at A having the usual rectangular socket B. The improved tool for actuating the plugeither in inserting it intothe boiler or removing it therefrom comprises a shank 1 having its ends 2 shaped to fit the socket B of the plug A, the usual shape of the shank being rectangular as shown and the end 2 is also rectangular, the flat faces of the shank 1 and the end 2 being unalined as shown.

Intermediate oi shank 1 and end 2 is a late ally extending circular flange 3and the shank 1 adjacent to the flange 3 is formed 55. v

with a circular shoulder 4.

Mounted on shoulder alis a cap nut 5 having an opening 6 to receive the shank 1 and shoulder 4; and to permit rotation of the nut on said shoulder. llut 5 is interiorly threaded and adapted to engage the threads on the plug A when it is desired to remove the plug from the boiler or to tighten the plug into the opening in the boiler.

It will be readily apparent that in using the tool for screwing in or out the wash out plug that the nut 5 when it is turned down on the plug will securely hold the end 2 in the socket B and prevent it from getting out of axial alinement with the plug and further- '[Q more that the nut 5 will reinforce the outer end of the plug and prevent the breaking of the plug in removing it.

What is claimed is 1-- V A wrench for removing and replacing 7 wash out plugs, comprising a shank rectangular in'cross section and adapted for engagement by a wrench, and an end correspondingly shaped, a circular flange intermediate of said shank and end, a circular shoulder eX- tending from said flange, and a cap nut polygonal in cross section supported by said flange and revoluble relatively to the shoulder, said cap nut being adapted to embrace and be secured to the top of a wash out plug and the end of the shank to engage in a correspondingly shaped opening in the top thereof.

In'testimony whereof I aflix my signature.
